Abstract (en)
A light detection device 1 includes an APD 11, a plurality of temperature compensation diodes 26, 27, and 28, and a circuit unit 3. The plurality of temperature compensation diodes 26, 27, and 28 have different breakdown voltages lower than a breakdown voltage of the APD 11. The circuit unit 3 puts any one of the plurality of temperature compensation diodes 26, 27, and 28 into a breakdown state. The circuit unit 3 includes a plurality of terminals 25 and a terminal 22. The plurality of terminals 25 are respectively connected to electrodes 29b of the mutually different temperature compensation diodes 26, 27, and 28. The terminal 22 is electrically connected to the APD 11 and electrodes 29a of the temperature compensation diodes 26, 27, and 28.
